Yolo County, CA Fire Regulations: Fireworks (2026)

All dangerous fireworks have been banned by ordinance throughout rural Yolo County since 2001 under Title 4 Chapter 2 of the Yolo County Code (Sections 4-2.101 through 4-2.605, added by Ordinance 1261 effective May 17, 2001). On June 3, 2025 the Yolo County Board of Supervisors unanimously approved the first amendment to that ordinance in nearly 25 years. The amendment (1) raises the administrative fine for a first-time illegal-fireworks violation in the unincorporated County from $100 to $1,000 per firework, with escalating fines for subsequent violations, and (2) prohibits the use of 'safe and sane' fireworks (those bearing the California State Fire Marshal seal under California Health & Safety Code Section 12529) within any portion of the unincorporated County that Cal Fire has mapped as a 'High' or 'Very High' Fire Hazard Severity Zone. Western Yolo County, including the Capay Hills and the communities of Rumsey, Guinda, Brooks, Capay, Esparto, and the Dunnigan Hills area, falls inside Cal Fire State Responsibility Area (SRA) where dangerous-fireworks discharge is also a state crime. Statewide, California Health & Safety Code Sections 12500-12728 (the State Fireworks Law) make possession or use of 'dangerous fireworks' (firecrackers, skyrockets, bottle rockets, mortars, M-80s, and any large or aerial device) without a state license unlawful regardless of any local ordinance.
